A lightweight fast-action specialty rod designed for the Czech Nymph technique where long, light leaders are used to catch wary, pressure-sensitive trout. It has a really light, responsive tip, but the lower 3/4ths of the rod is stiff to help you "drag" weighted nymphs through likely feeding areas. This 4-weight version is for slightly heavier leaders than the 3-weight and allows you to handle larger trout. GLX really makes a big difference with this technique because it's so light and so sensitive
